MAINTENANCE - CLEANING
1) Remove the detector from its base.
2) Smoke entry areas and thermistor area: use a small,
soft bristle brush to dislodge any obvious contaminants
such as insects, spider webs, hairs, etc.
3) Smoke entry areas and thermistor area: use a small
vacuum tube or dry, clean, compressed air to suck up or
blow any remaining small particles away.
4) Wipe the exterior housing of the detector with a clean,
damp, lint-free cloth to remove any surface film that can
later attract airborne contaminants.
5) Install the detector onto its base again.
6) Test the detector.
MAINTENANCE - BATTERY REPLACEMENT
When a low battery condition is indicated,
both batteries must be changed altogether.
During this procedure the linking switch must NOT
be touched at all !
1) Detach the detector from its base.
2) Extract the batteries cover.
3) Extract the batteries.
4) Insert the new batteries into their holders,
oriented as per polarity marks.
5) Reinstall the batteries cover.

WARNINGS AND LIMITATIONS
Our devices use high quality electronic components and plastic materials that are highly resistant to
environmental deterioration. However, after 10 years of continuous operation, it is advisable to replace
the devices in order to minimize the risk of reduced performance caused by external factors. Ensure
that this device is only used with compatible control panels. Detection systems must be checked,
serviced and maintained on a regular basis to confirm correct operation. Smoke detectors may respond
differently to various kinds of smoke particles, thus application advice should be sought for special
risks. Detectors cannot respond correctly if barriers exist between them and the fire location and may
be affected by special environmental conditions. Refer to and follow national codes of practice and
other internationally recognized fire engineering standards. Appropriate risk assessment should be
carried out initially to determine correct design criteria and updated periodically.
